The reaction below can be used as a laboratory method of preparing small quantities of Cl_2(g).
Cr_2O_7^2- + H^+ + Cl^- yelids Cr^3+ + H_2O + Cl_2(g) ( not balanced)
If a 67.4-gram sample that is 98.5% K_2Cr_2O_7 by mass is allowed to react with 300mL of HCl(aq) with a density of 1.15 g/mL and 30.1% HCl by mass, how many grams of Cl_2(g) are produced?
